Transport Canada Recall - 2019055 - GENERAL MOTORS

Issue:
On certain 3500 series trucks, the level sensor in the front fuel tank may malfunction. In rare cases, the front fuel tank may over-fill and expand, causing it to contact the driveshaft. Operators may hear a grinding or knocking noise if this happens. This could create a hole in the tank and cause a fuel leak. Note: This problem only affects cab and chassis models equipped with a gasoline engine and dual fuel tanks.

Safety Risk:
Leaking fuel, in the presence of an ignition source, creates the risk of a fire.

Corrective Actions:
The company will notify owners by mail. Owners will be instructed to take their vehicle to a dealer to have the rear-tank fuel-pump module replaced. Dealers will also inspect the front tank and replace if necessary.
